Italian research agency fights COVID-19 with smart shelters using biocomposites

Due to the COVID-19 pandemic, the demand for intensive care beds is rapidly increasing worldwide. The SOS - Smart Operating Shelter - project is an important resource, enabling rapid set up of mobile healthcare units for the treatment of infected patients.
The SOS project is led by the Italian research organization CETMA (Brindisi, Italy), which is also a leader in composites research and by RI SpA (Lecce, Italy), a group leader in modular building construction. The project is co-funded by the Apulian Region (Italy) within the INNONETWORK funding measure. A multidisciplinary Apulian partnership is also involved in the project: Politecnico di Bari, ENEA, ENA Consulting, Kinema, Mespo and Protom Group SpA.
As part of the SOS project, architectural layouts were designed and engineering solutions investigated to quickly set up mobile healthcare units that are easy to assemble and install, with smart and low environmental impact sandwich panels. The know-how acquired in this project will be made available to the regional health system.
Eco-composite panels, multifunctional solutions
One of the main objectives of the SOS project is the development of advanced and eco-friendly materials for structural panels that are multifunctional, smart and reconfigurable, ready for use in just a few hours after arrival, without involving specialized personnel for installation. Research and development issues addressed include:
- Innovative sandwich panel inner cores using bio-based polyurethane systems and/or revcycledPET foam;
- Eco-friendly composite laminates for external sandwich panel skins using natural fibers and bio-based polymers;
- Coupling of the core with the outer skins;
- Ability to integrate technical compartments for electrical/IT/medical gases and radiation protection systems;
- Reduction of overall dimensions, study of connection systems for facilitated assembly;
- Pressure-based containment with particular reference to the seals of the movable and extendable elements; conditioning and filtering systems for clinical environment; surfaces and equipment suitable for sanitization; control and maintenance of indoor comfort, even under extreme climatic conditions;
- Operating efficiency of all components, integration of automation solutions, correct operation of each component after each handling and transport;
- Certification of clinical environment per government regulations.
- Acquisition systems, analysis, design, monitoring and interfacing with intelligent decision support and optimized methodologies, in order to ensure compliance with high performance index of all the integrated services deliverable within the complex innovative structure.
In 2019, CETMA developed an innovative bio-based sandwich panel comprising an inner core made from plant-based and/or recycled PET foam, while the outer skins are composite laminates made with natural fibers and polymeric resins obtained from renewable sources.

In collaboration with the SOS project team, CETMA also devised a technical solution for vertical/horizontal partitions, consisting of three elements: 1-sandwich panel, 2-systems cavity and 3-inner lining panel. Such a solution is very flexible and allows modifying structures for various intended uses.
CETMA is also engaged in the development of multifunctional structures combining:
- Self-supporting structure: sandwich panel application for walls, partitions or ceilings;
- Systems integration: new solutions to more effectively integrate wiring and connections for power supplies, medical gases and data/monitoring systems;
- Smart monitoring: integration of smart environmental sensors and/or electromagnetic (EM) shielding.

No longer dependent only on their green credentials, some suppliers of bio-based fibers and resins are competing on price and performance.
JEC World will be held March 14-16 in Paris. CW previews some of the products and technologies that will be at the show.
The structural properties of composite materials are derived primarily from the fiber reinforcement. Fiber types, their manufacture, their uses and the end-market applications in which they find most use are described.
